Moon on the horizon mistaken for a UFO at Arras

Summary

On 17 March 1978, a witness in Arras (Pas-de-Calais) watched a round luminous object drift slowly northeast for ten minutes without sound. The gendarmerie found no further explanation, but GEIPAN classified the case PAN A after determining the phenomenon matched the appearance of the Moon near the horizon. The witness did not mention the Moon, suggesting fatigue and mood influenced the interpretation. Despite an accurate description, it is another misidentification of a common astronomical object.
